6.6 Single and Double Displacement Synthesis Decomposition Single Displacement Double Displacement

Single Displacement Single Displacement: One element replaces another in a compound Non-metals replace non-metals Metals replace metals Two people are dancing, and someone cuts in…

Single Displacement Single Displacement: Be careful! Follow rules of metal replaces metal, and non-metal replaces non-metal If A is a metal, B is a non-metal……what is C?

Single Displacement Example 1: Zinc reacts with copper (II) sulphate to make ________ and __________. Word equation: zinc + copper (II) sulphate  ? + ? Formula Zn + CuSO4  ___?____ + __?___

Single Displacement Zn + CuSO4  ___?____ + __?___ Zinc will form Zn2+ Copper will form Cu2+ Sulphate is the complex ion SO42- Can copper and zinc form a compound? ____ Can sulphate and zinc form a compound? ____ Why?___________________________________

Single Displacement Zinc + copper(II) sulphate  copper + zinc sulphate Zn + CuSO4  Cu + ZnSO4 More examples in page 240 in your textbook

Single Displacement Magnesium reacts with carbon dioxide to form magnesium oxide and carbon Word equation ____ + _____  ____ + _____ Chem equation ____ + _____  ____ + _____ Balanced equation ____ + _____  ____ + _____

Double Displacement One element in a compound displaces or replaces an element in a compound Many happen between ionic compounds Non-metal switches with non-metal

Double Displacement AgNO3 + NaCl 
